Doppler Broadening

(broadening of spectral lines due to velocities of the photon sources)

Doppler Broadening is a width of Spectral Lines due to the motion of the particles that emit photons, such as thermal motion. By studying the shape of the line, inferences can be made about the source of the radiation.
